rumanos CLEANER.

Application and Aprn 11,1928.- seriai Ne. eeaeea This invention relatesto means for cleaning the radiator of a furnace, the general object ofthe invention being to provide a rotary member on the bottom of theradiator for collecting the soot and dust, with means for rotating thesame and with a spiral associated with the rotary means for scraping thesoot and dust from the rotary member and either forcing it into theopening. in the 10 dome of the radiator so that it will drop into thefurnace or for moving theV soot Vand dust into the 'clean-out opening inthe i furance. r y f Another object of the invention is to provide adeflector member arranged alongside the spiral which helps the spiral toremove the material from the rotary member, with means for reversing theparts to place the deflector member on either side of the spiral. lAnotherl object of the invention is to` so form'the parts that 4they canbe placed in position through the clean-out opening and removedtherefrom, with means for detachably holding the spiral supportingmember inthe clean-out opening.

This invention alsoV consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated` in the accompanying drawingsand specifically .pointed out in the appended claims.

In describing my invention in detail, refdrawings wherein likecharacters denote like or corresponding parts throughout the severalviews, and in which---'` Figure 1 is' an. elevation with parts insection, of a furnace, showing the invention in use.

FigureQ is a section on line 2-2 of Figure 1. c v y Figure 3 is a frontend view of the invention.

Figure 4 is a rear end view thereof.

Figure 5 is a section on line 5-5 of Figure 3.

Figure 6 is a fragmentary view of the rotary member, showing the meansfor connecting the sections thereof together. Figure 7 is a section online 7-7 ofy Figure 6. n

As shown in these views, I place a ringshaped plate 1 in the lower partof the annular member of the radiator A of the adjacent section.

erence will be had tothe accompanying` furnace, this plate beingformedof sections,

engaging'a keyhole-shaped opening '3 in the The sections must be` so`formed that they can'be passed through the clean-cut opening B ofthefurnace so that they can be readilyv put in place.v in the radiator orremoved therefrom. The outer periphery of the. plate is formed withftheteeth 4. A cylindrical member 5 has a cross piece 6 at its frontend in.which is journaled the stem 7 of a screw or spiral 8 so that the spiralis rotatably supported by the member 5. The outerr end of the stem 7 isshaped to receive a crank handle so that the spiral can be rotated. 1 nf Y l The member 5 is .removably held in the clean-out opening B-by theplates '.9 atjtached to its sides and frictionally engaging` the wallsof the clean-'out opening and by the set screw 1G threaded int-o a holein the top of the member 5.and engaging the top wall ofthe clean-outopening, lthis screw acting to hold the member 5 against the bottom ofthev clean-out opening. The bottom part ofthe member 5 is provided witha threaded hole 11 so that it can be reversed and the screw 10 placed inthis .hole 11 when i;

the vspiral is to be turned in an opposite direction. When the member 5is properly positioned in the clean-out opening, the spiral will rest onthe rotary plate 5 and a 'gear 12 is fastened to the spiral anappreciable distance from its front end, the teeth of the gear engagingthe teeth 4 of the plate so that whenthe spiral is rotated, the gear .12will impartI rotary `movement to the plate 1.

A deflector plate 13 of lcurved shape `in cross section is fastened tothe member 5 and parallels the spira-l, this deflector plate preventingashes, dust, soot or the like from being carried around by the plate 1and causing such material to be moved od the plate by the spiral. Whenthe opening 14 will be rotated so that the material on said plate willbe scraped therefrom by the spiral and the deflector 13 and forcedthrough the opening ll into the furnace. In radiators Where the openinglet is not opposite the clean-out opening, the member Y 5 is reversedand the screw l0 placed in the It is thought from the foregoing descrip#tion that the advantages and novel :features of my invention will bereadily apparent.

- It is to be understood that I may malte changes in the constructionand in the combination and arrangement of the several parts, providedthat such changes fall Within the scope of the appended claims.

What I claim is.:-

l. A device forl cleaning a radiator of a furnace comprising aring-shaped plate placed in the annular chamber ofthe radiator androtatably supported therein, a supporting member removably held in thecleanout opening of the furnace, a spiral rotatably supported by saidmember and entendino' over the plate and adapted to remove the materialfrom the plate means for rotating the spiral andthe plate and adeilector member supported by the supporting member and contacting witha portion of the spiral. v l

2. A device for cleaning a radiator of a furnace comprising aring-shaped plate placed inthe annular chamber of the radiator androtatably supported therein, a supporting member removably held in thecleanout opening of the furnace, a spiral rotatably supported by saidmember and extending over the plate and adapted to remove the materialfrom the plate, means for rotating the spiral and the plate, a deiectormember `supported by the supporting member and cylindrical member, aspiral rotatably sup ported thereby, means for removably hold ing Ythecylindrical member in the clean-out opening of the furnace, said spiralextending acrossthe plate and contacting therewith for Vremovingmaterial from the plate, a gear fastened to the spiral and engaging theteeth on theplate for imparting movement to the plate when thespiral isrotated and a deflector vmember of` 'curved vshape in cross sectionattached' to the cylindrical Vmember and contacting the inner portion ofthe spiral.

Ll. Means forrremoving foreign matter from the radiator of a, furnacecomprising a sectional ring-shaped plate rotatably mounted in theannular' chamber of the radiator, teeth on the periphery Aof the plate,aV cylindrical member, a spiral rotatably supported thereby, means forremovably holding the cylindrical member in the clean-outopening of thefurnace, said spiral extending across the plate and contacting therewithfor removing material from the plate, a gear fastened to the spiral andengaging the teeth on the plate for imparting movement to the plate whenthe spiral is rotated, a detiector member of curved shape in crosssection attached to the cylindrical member and contactingthe innerportion of the spiral and means for permitting the' cylindrical menr berto be reversed in the clean-out opening whereby the deflector member canbe placed on either side of the spiral.

In testimony `whereof I aiiix my signature.
